openSUSE at Chemnitzer LinuxTage 2017

I went to Chemnitzer LinuxTage last weekend. That was a successful open source event.

openSUSE has got a lot of positive feedback. Some people changed from Ubuntu to openSUSE Tumbleweed and are happy.

There was some misunderstanding with the new release development of openSUSE Leap. Some people thought that would be a second rolling release by openSUSE. After explaining that we want to do that only in the development phase for achieving a more stable operating system and we will have a release day every year again, these cusomers have been happy again and like this idea. More stability is a good reason. 🙂

invis server had his meeting about their new project openSUSE SMB. One openSUSE customer was interested for this project and I brought him to Stefan. Some booth visitors want to visit our next oSC in Nuremberg.

We had more customers than in the year before. Somtimes guys asked how to change to us and to contribute. Linux beginners wanted to have live CDs. We burned flash drives with Tumbleweed live images for them.

Sunday we had a raffle at our booth. The award was a big chameleon. You can see the winner on the picture.At the end I took part of the raffle by Thomas Krenn AG. 🙂

They produce server hardware and storage. Their first award was a low energy server which I won. That‘ s ideal for students like me. The best thing is that this server hardware is supported by openSUSE.

Chemnitzer LinuxTage was a fantasic open source event like every year. Thanks for the sponsoring!

tcpdump of a docker container

You create docker containers and many tools are missing. As an example: tcpdump

So I was looking for a solution for sniffing the traffic from outside of the container. It is recommended to setup an additional (tcpdump) container and to use it with following network connection:

docker pull adamoss/docker-tcpdump

docker run -ti –net=container:${id} adamoss/tcpdump port https or port http

 

You can specify different ports and save the data in a file. The id is the name of the container and the „–net=container:“ is saying that you want to have input/output traffic of the docker container like the command would be executed on the same system.

Running for the openSUSE Board

Hi! I‘m Sarah Julia Kriesch, 29 years old, educated as a Computer Science Expert for System Integration, and currently studying Computer Science at the TH Nürnberg.

 

Introduction and Biography

I am a Student at the TH Nürnberg, Student Officer for Computer Science (Fachschaft Informatik) and a Working Student (Admin/ DevOps) at ownCloud. I changed from working life to student life this year. I have received the scholarship „Aufstiegsstipendium“ (translated „upgrading scholarship“) for students with work experience by the BMBF.

I have got 4 years of work experience as a Linux System Administrator in the Core System Administration (Monitoring) at 1&1 Internet AG/ United Internet and as a (Managing) Linux Systems Engineer for MRM Systems (SaaS) at BrandMaker. MRM Systems are systems for project management in marketing (Marketing Ressource Management Systems).

I used SLES/ openSUSE during my German education of information technology for the first time in 2009. In the company I learned installations with YaST. I wanted to know more, which was the reason for going to conferences and expos. I tried to educate myself (with community support and vocational school) until the end of my 2nd year. oSC11 was the time stamp for meeting the openSUSE Community.  Marco Michna wanted to become my Mentor in System Administration and gave me private lessons until his death. I got a scholarship for further education (a free Linux training) by Heinlein. Both were a good base for starting in the job after the vocational training act.

I wasn‘t allowed to contribute to openSUSE during my last year of education, because my education company didn‘t want to see that. They filtered Google after all contributions in forums and communities. That‘s the reason why I am using the anonymous nick name „AdaLovelace“ at openSUSE. I had to wait for joining openSUSE again until my first job where I worked together with Contributors/ Members of Debian, FreeBSD and Fedora.

I started with German translations at openSUSE with half a year of work experience. Most of you know me from oSCs (since 2011). I was Member of the Video Team, the Registration Desk and contributed as a Speaker. Since 2013 I am wiki maintainer in the German wiki and admin there. Since 2014 I am an active Advocate in Germany. I give yearly presentations, organize booths and take part in different Open Source Events. As a GUUG Member (German Unix User Group) I asked for a sponsorship for oSC16. I hold my first (English) presentation about performance monitoring there then.

This year I have joined the Heroes Team and the Release Management Team. I founded the Heroes Team with my friends during the oSC16 because of the spam in the wiki. I became the Coordinator for this project. I am Translation Coordinator now, too. I was responsible for the documentation of openSUSE Leap 42.2. So I wrote a lot in the English wiki this year. I was interviewed (as an Advocate) by the Hacker Public Radio at the FOSDEM 2016.

Some of you know me from different mailing lists. That‘s the best way to reach me.

I love openSUSE and pick up tasks, if I see something to do where I can help with my Sysadmin/ Coordination/ Documentation/ BPM skills. Free periods ( Monday & Tuesday) are reserved for openSUSE Contributions. If somebody asks me for technical help (unimportant whether programming, infrastructure or communication), I‘ll try to find a solution.  I learned to work agile (Scrumban in System Administration) which I want to transfer to my teams in open source projects.

Issues I can see

I want to improve the cooperation between openSUSE and universities/ TH Nürnberg as the founder of the Open Source AG there.

openSUSE should be one of the main distributions on AWS (main AMI).

The openSUSE Infrastructure should be easier to achieve for openSUSE admins, so that we can react on escalations very fast.

Role of the Board

My goal is to have happy customers and developers. That‘s what I want to achieve as an Advocate and (perhaps) as a Board Member in the future.

We should live freedom in the community. Everybody should do what he likes. I don‘t like bossing. But I want to help in leadership with coordination and solutions where needed.

Why you should vote me

  •  I am a geek(o).
  •  I like new technologies and learning.
  •  I know most important people in the community.
  •  I learned coordination in my first job, which I can use as a Board Member, too.
  •  I am educated by communities.
  •  I have got an education in information technology.
  •  I contribute to different parts of the project (technical and non-technical).
  •  I have got a big open source network (openSUSE, ownCloud, GUUG, …).
  •  I have got international work experience.
  •  I love openSUSE.

 

Aims/ Goals

We should improve openSUSE and hold the position of being one of the best Linux distributions.

I want to be open for cooperation with other Linux/ open source projects.

openSUSE on ownCloud

It is Christmas time and I have got cookie cutters by openSUSE and ownCloud. What can you create as a happy Working Student at ownCloud and an openSUSE Contributor?

Normally you deploy ownCloud on openSUSE. But do you know the idiom „to be in seventh heaven“ (auf Wolke 7 schweben)?

I want to  show you openSUSE Leap 42.2 on ownCloud 9.

 

opensuse Leap 42.2 on owncloud 9
opensuse Leap 42.2 on ownCloud 9

9.1 is the latest release, and 7 not up to date and insecure for the openSUSE chameleon. The second reason is that the chameleon has got a perfect place on the cloud.

You can watch the success in both projects!

I wish you all a merry christmas and a lot of fun with your cookie cutters!

OpenRheinRuhr 2016

openSUSE took part of the OpenRheinRuhr like every year. This year we were sponsor and I was the organisator of that and the booth. Additional to that I gave a presentation about the new release of openSUSE Leap 42.2. It was full and many people were interested for the news in the community. I do that yearly and openSUSE talks are standard there since 3 years. Many people are saying that I am not allowed to be missed as a Speaker. The second standard speaker of openSUSE is Axel. His talk was about SUSE Studio and GNU Health this year. We represent openSUSE with our talks at the OpenRheinRuhr.

img_0128At first all Contributors got their T-Shirts and the table should be full with marketing material. Christian and Simon were looking for our Customers during my presentation. All people laughed afer hearing I would be a Working Student at ownCloud now and we want to have a cooperation booth (openSUSE / ownCloud) next year, because I want to continue with oganizing. The question with 32 bit support popped up again and the audience was happy that we have got Tumbleweed for that. openSUSE in the Linux ranking and our plans were questions, too. Top Linux Speakers (from Germany) were in the audience. They are my new focus for marketing, because they can represent openSUSE during their presentations and are really enthusiastic.

After lunch Simon asked me whether he can go to talks. I said: „Of course! You are an Advocate and should learn here, too. There aren’t better options than talks during such events for getting qualified people for the booth. I know why I look after enough people for a booth (more than 2) during conferences and expos.“ Simon smiled, told us the times and used it for learning in 2 talks.

We have got new interested volunteers for openSUSE. One guy wants to join the heroes team and a woman wants to become an Advocate. Other distributions want to cooperate, too. Gentoo created pins with our logo for our fans. And fsfe came to us with their cloud stickers and shown us the normed SUSE cloud on their stickers. All were happy. We had a lot of fun!

We had a conference party in the evening. We had so many sponsors that we were allowed to get free beer (for all) and grillables (for Contributors). Thanks to all sponsors! It was a nice evening.

The ZDF (Zweites Deutsches Fernsehen) was available at the second day. They went through the hall with their camera. Self filming (with webcam) in front of the ffmpeg booth was most interesting for them. I had to give ownCloud support and the webcam security (of openSUSE) was a highlight for customers. We were asked after our release day very often and I showed my presentation slides again and again. At the end Christian and I won books (Scrum and LibreOffice) at the tombola. The talk of Axel was successfully, too.

img_0133We enjoyed the OpenRheinRuhr and want to take part of such an Open Source event ( with a minimum of 2 talks) next year again. We know what we want to tell then, too. 😉

That was great!

openSUSE Conference 2016

June 22 until June 26 was the openSUSE Conference in Nuremberg. The location was the Z Bau. We had a lot good presentations from Security, YaST News, Release Management until Infrastructure, Monitoring and Configuration Management.

That was the first conference with  my own presentation in English. The talk was about monitoring and stress tests, something what I have done in the last years in my job. At first I was nervous. But I had many good friends around me who  took it away. 2 of them gave presentations, too. Oliver talked about USB in the kernel development and Christian made a quiz.

It was a good place and time for team discussions. Christian and I wanted to speak with the Infrastructure team about the situation with wiki servers in United States. We needed a SUSE guy from there and found Craig. After that we created a Infrastructure meeting and the openSUSE heroes team exist since this time. I am the Coordinator for a new wiki setup and openSUSE Contributors can get access to the Infrastructure. That was the highlight of the conference!

We took part of a Nuremberg tour through fermentation cellars which was really interesting. We discussed a lot and were able to see people in the community from everywhere on the world. The SUSE band played music in  the evening and we had a lot of fun!

Thanks!

FOSDEM Day 1 and Day 2

 

I have slept in the Hotel Evergreen. The breakfast was very small. The room and wireless were ok.

I have got luck, that other German people wanted to go to FOSDEM, too. They have been in the same hotel and knew the way from the last years. They shown me the different houses and I went directly to the openSUSE booth, where some of the community were available. CentOS was our neighbor. We all have got gloves and tee shirts by them. They have got beer by us.

I have got new t shirts. I wore one of last November with the new release. I was a little bit surprised, that we would have a new one again. DVDs with Leap were available, too. They were burned in December – the last month of Open Source Press. They closed. That was my first question, I asked Richard. He told me, that they have closed for books, but would produce DVDs for a longer time.  It was a full day for us at the booth. We disposed beer and t shirts. I new many faces from OpenRheinRuhr, FrOSCon and GUUG. It has been more famous faces I thought to know. I will see many of them at the FFG of the GUUG again.

 

I made a trip through the house to the other booths. People of our DevOps meetup group wanted to have Jenkins stickers. I took some of them. I bought a tee shirt by them, too. After that I heard, that they would have Jenkis meetup groups everywhere on the world, but not in Germany at the moment. We have got so many meetup groups for it in Karlsruhe and not Jenkins? It would be too late for me, because I want to change the town in May. I will give it to our organisators and take it with me for Nuremberg.teamFOSDEM

 

I was interviewed by the Hacker Public Radio.  They wanted to have a interview at every booth. My sound wasn’t very good after a common cold, but I did it. All my Open Source friends were coming to me at the booth. I gave Douglas some hints for the next oSC. I don’t know at the moment, whether I can come, because that will be my second month living in Nuremberg again. In the evening of the first day some community members wanted to go out for eating and drinking. At the end we let it for being fit for the next day.

At the next day the FOSDEM wasn’t so full like the day before. At the beginning I created a plan for visiting talks. I have got the next interview with a PhD student of the TU Berlin for his doctor thesis. His doctor father told him wrong things about the difference between Microsoft and Linux projects. Some things have been right, but our support can be faster than the support of Microsoft. And we get more and more customers by them.

 

My first visit to a talk was Literate DevOps for Configuration Management. I hoped a little bit more about this presentation. During the presentation I thought about doing every step with sed. My directly neighbor was another student at the German distance teaching university (Master Praktische Informatik). He wanted to know, how you can get more support by the university. I told him about our facebook group, newsgroups and irc. He was surprised, that the university would have irc channels. After his stories about his first studying (business information technology) und Hagen I am happy, that I want to change to Nuremberg. I don’t need a education degree by a university on the level of a university of applied science.

 

After that I went to Big Data meets fast Data. I have got luck for getting a free place. It was a presentation about different in-data-memory databases. That was very interesting for me. After that I took a conference waffle with me to the booth. I saw some people of B1 Systems again.

At the end of the day I have got a openSUSE box by Richard. I am looking forward to the future of the openSUSE box (perhaps without Open Source Press).

Thanks for the wonderful 2 days and the Travel Support. That was my first chance for coming to FOSDEM, because normally that’s the time for learning for the university. I have done a break this semester. I was able to take a lot with me. Next year I will have learning on the program at this time again.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Arriving in Brussels for FOSDEM

Today I left the company a little bit earlier for getting the train to Brussels.

What for a surprise! A ex colleague of 1&1, who works as an architect, was sitting across from me since Mannheim. We told us about the changes in the last years, what would be new and what we want to have in the future. We had to wait for the next train in Cologne for a 3/4 hour. We used this time for eating. We met another ex colleague, who is a freelancer now. WE spoke about Cologne and the life there. I have lived 8 years of my childhood in this town.

We began a discussion about good literature for Computer Science and getting DevOps into a company:

-The most important book for learning programming and algorithms in theory is Introduction to Algorithms. You can find additional videos matching to the book on the homepage of the MIT.

-I go to every presentation of the Java User Group Karlsruhe. Many companies are working on the base of Clean Code. That’s the practical part for good programming. Every programmer should read this book.

-You can learn operations with an own server at home or with training on the job in companies. I have taken the first way during my education as a Computer Science Expert and have got a job as a Junior Linux System Administrator at 1&1 after that. That was a big jump for me and I enjoyed my junior time. Our team has got the specialization „Monitoring & Infrastructure“. We were Sysadmins for the root monitoring system, the customer DNS and the internal DNS. I wanted to learn more and switched to an international provider for MRM systems. We are a small business, but the leader on the European market. I was responsible for all in the system administration of our customer systems. Different Open Source Software is integrated into our software and working in this area of Cloud Computing is part of Big Data. You can have fun there and grow.

The combination of all is a dream…

We took different ways after arriving Brussels. I went to the hotel Evergreen. I thought, that would be a good idea for bowing out of Evergreen in openSUSE. We‘ ll miss this project.

 

I am looking forward to see many familiar faces at the FOSDEM.
